Characterization of fiber bragg grating as temperature sensor for pipeline water leakage inspection / Siti Nabilah Muhammad Ghazali

In this work, Fiber Bragg Grating (FBG) was characterized as temperature sensor for pipeline water leakage inspection. This is because FBG is sensitive to temperature, thus make it a potential device to perform pipeline water leakage inspection. Bragg wavelength An was measured by Tunable Laser Source (TLS) as light source and optical spectrum analyzer (OSA) to observe the reflected Bragg Wavelength at temperature from 24 °C to 40 °C. Analysis is performed to define the relationship of As with temperature based on the collected data. The temperature sensitivity of is 9.2 pm/°C and 9.8 pm/°C was obtained for FBGl and FBG2 respectively.
